    13 I am indebted to the Borough Engineer, Mr. G. F. Carter, for the following information:- A constant supply of water was maintained throughout the year, and has been satisfactory both in quality and quantity. Monthly analyses of the water were made at the five pumping stations, and in many cases at more frequent intervals. The Corporation's wells are all in the chalk, and a sample analysis is as follows:— Clear and bright. Hardness—Temporary, 16.3 deg. ,, Permanent, 3.7 deg. No B. Coli in ]00 c.c. No Streptococci. No acid in 100 c.c. The supply during the year was from the Corporation's Wells 2,233,095,210 Metropolitan Water Board in Bulk 462,709,000 2,695,804,210 gallons. This works out, on an average population basis of 240,000 (1932), at a consumption of 30.69 gallons per diem per head. Rivers and Streams. There are only small streams or ditches. These have been kept in a good state. Drainage and Sewage. Extensions of the sewerage system have been made to keep pace with the growth of the Borough, in particular in the new area of Addington which was added to the Borough in 1928, Over £36,000 has been expended in main sewers and surface water drains. At the sewage disposal works a.t Beddington, three Activated Sludge plants are in operation dealing with 3½ to 5 Million gallons per day.
